Application filed December 27, 1905. Serial No. 293,442.

two trains are located on the same track and for permitting communication between said trains while they are inmotion or at rest, thus affording means for the prevention of collisions; and it consists in certain peculiarities of the construction, novel arrange.- ment, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide an apparatus of the abovenamed character which shall be comparatively sim- -ple and inexpensive in construction and use,

the parts of which shall be so arranged as to automatically give an alarm on each of the trains or cars at the instant they are both c'ated on the same track whether they are moving in the same or opposite directions or whether one or both of the trains or' cars" are at rest.

Other objects and advantages of the invention will:be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in

I .which Figure 1 is a cross-sectional view of a portion of the cab of a locomotive or motor-car, showing it mounted on wheels resting on the rails of a track. Fig. 2 is a view, partly in" section and partly in elevation, taken'on line 2 2 of Fig. 1 looking in the direction indicated by the arrows. Fig. 3 is an enlarged vertical sectional view of one of the supports for the contacting devices for the electric conductors on the railway-rails, showing it shortened for the convenience of illustration. Fig. 4 is a similar view showing a modification in I the construction of the support, as well as in the contacting devices, and also illustrating a supporti%, device for one of the operatinglevers; ig. 5 is a detached perspective view of one of the modified forms of the contacting devices. Fig. 6 is a diagrammatical View showing the electric connections between the conductors on the rails and an alarm-bell and telephone and also showing a switch for controlling the electric current. Fig. 7'is a perspective view of a portion of two railwaytracks, showing the switch therefor and the arrangement of the electric conductors on the main rails thereof. Fig. 8 is an. inner face view of portions of two alined rails, showing the manner of connecting the conductors at their ad acent ends. Fig. 9 IS a cross-sectio'nalview' taken on line 9 9 of Fig. 8; and

Fig. 10 is a perspective view of a portion of one of the rails, showing the means for supporting the conductors thereon.

Like numerals of reference refer to corresponding parts throughout the different views of the drawings.

In order to carry out my invention in'practice, it will be understood thatthe locomotive-cab or motor-car or a car of each train should be equipped with certain devices hereinafter to be described; but as their equipments will be identical it is only necessary to describe the construction and arrangement of the parts for one description.

The reference-numeral 15 designates a portion of the cabof-the locomotive or a part of a motor-car or other car, either of which may of them, in the following be of the ordinary or any preferred construc a tion and, as usual, is mounted upon wheels 16, which travel on rails 17 in the. rdinary manner. Each of the rails 17 of "the track has supported on its inner surface in parallelism, one above the other, two electric 0on ductors 18 and 19, which may extend the en-,

the length of the track, and at breaks, such as at crossings and switches, may be turned down below the base of the rails, as shown at 19 inFig. 8 of the drawings. These con ductors rest in the grooved outer ends of lat- Halli-extending projections 20 on plates 21, whic. rest on suitable insulating material 22, interposed between them and said rails and secured to the inner, surfaces of therails, as,

will be cl'earl understood by reference to Figs. 3, 8, an 10 of the drawings.

Mounted .on the lower surface'of the bot Ioo tom of the cab or car 15, near each of its j,

sides, is a depending bracket 23, each of which is rovided'with vertical channels 24 and 25, tne former being for the reception of electric'conductors and the latter for an op erating lever or bar 26, aswill'be present explained. The brackets ,23 are seciared vy to,

, so that their outer surfaces will be in a vertiat its lower end an enlargement 29, which is of electric conductors. Leading horizontally,

directly above each of the brackets 23, is an 1 upright 40, each of which has a vertical chan- '-eratin -bars 26, each of which is nested ortion of, the channel 3'1v in the arm. 2.8 Wit .1 the rails,.each of which consists of a metallic lower end, by means of hinges 27, adependin Fig. 4 a modification in the-construction of ra ed at a suitable sni ch the bottom of the cab or car at proper points,

cal line near. the inner surfaces of the rails 17. Each of the brackets 23 has secured to its ing arm 28, which may be of any suitable size, form, and material, butpreferably has provided in its outer portion with two horizontal recesses 30, in which are located the contact devices for the conductors 18 and 19 on the rails of the track. Eachof the arms 28 is provided with a vertical channel 31, which communicate with the channels 24 of the brackets 23 and are also for the reception from the lower portion of the channel 31 are channels 32 and 33, through which the con--- ductors34 and 35 located in the channels 24 and 31,, will pass, whichconductors are secured at their lower-ends to shafts 36, vertically journaled in the enlargement 29 on each of the-arms 28, each of which shafits has mounted thereon a' grooved Wheel 3 7'to con; tact with theconductors on the rails. Each of the arms 28 has an inwardly-extending projection 38, to which is secured one end of a spring 39, the other end of which is secured to the bottom of the cab or car at about midway betweenitssides. Located on the up-' per surfaceof the bottom of the cab or'car,

nel 41 to registeriwith the channels in said brackets. and are also for the reception of] opoosely conto the middle portion of a curved han- J die 42, which is pivotally connected at one of 1 In Fig. 4 of the drawings I have shown-a modification in theconstructionof the suppolite for the contacting devices, which consists in forming the lower portion of the cha n nel 2 t in the bracket 23 with a recess 24 and a recess 31* to receive coils 4.4 on: the conductors and 35., which must necessarily yield in order to allowthe arms to be turned on their-hinges. I have also shown the contacting deyicesfforthe conductors on shoe or plate 45, having in its outer edgea' groove 46, andon its inner rtion an aperturedfrojection 47., to whicl the conductors $34 an are-connected at theirlower ends; Thesemodifi ed; 'contacti ng devices are .located in horizontal recesses 30, as are the wheels. 37 in theotherconstruction. Lo-

point at one side of the cab or-car is a battery 48, which is in electric connect on with an alarm-bell 49 and which; batterizis also. in electric -connection,through conductors and contacting devices, -i

with the conductors 18 and 19 on the rails on one side of the track. Electrically connect-y consists of a casing 53, having at one of its ends a tubular portion 54, in which is located a push-pin 55, around the outer portion of which is secured a spring 56, employed for retracting it. Located longitudinally in the casing and separated from each other by means of insulated material 57 are a series of springs 58, 59, 60., 61, 62, and 63, which projectfrcia the insulated end of. thecasi-ng, as is clearly shown i-nFig. 6. of the drawings. Leading from one terminal of the battery 48 to the upper contact device- 37 is the conductor 34, and leading from the other terminal of said battery-is a conductor 64, connected with the central contact spring 62 at one side of switch 52. vW'ith the central conta'ct spring 59 at the other side of switch 52 is connected: the conductor 35, leading" to the lower contact device 37,communicating with track-conductor 19. The central contactsprings62; and 59 at opposite sides of switch 52 are normally in communication with innor contact-springs 61 and 58, respectively, p

which have connection with conductors 67 and 66, leading to the terminals of the alarm device49, which is thus normally in circuit ,with battery 48 and track conductors 18 its ends to, a lug 43 on the upper end of each of said uprights. I

and Y19, so, as to permit said alarm, to be sounded when the circuit is closed between said track-conductors. The lower end of the central switch-springs 62 and 59 have reverse inclines tobe'en aged by the tapered end of button 55,.Where 59 are moved, out of, contact with the nner springs6l and 68 to cut the circuit connections of alarm 49 with battery 48 and conductors 18- and 19- and simultaneously to] make communication from, said-central springs. 62 and 59th the outer springs 63.-

and 60 at opposite sides of the switch 52 and with which are connected the respectivecom ductors 68 and 69, leading. to and from the terminals of the telephone 50, wherebyiit will be seen that the telephone is cut in circuit with battery 48 and track-conductors 1 8 and '19 immediately upon breaking the circuit connections of alarm 49.

From theifcregoing and by reference to the drawings it will, be seen and readily when. the levers or bars 26 are drawings, the lower ends contactwith the inner surfaces y when said button grossed endwise said central springs 62 as shown in Figs. 1,, I

. and that an alarm on the bell 49'will be autoof the upper ends of the arms 28, thereby l holding the same in vertical positions, so that their contact devices will rest a ainst the conductors 18 and 19 on the rai s. If for any reason-for instance, if ,there is snow or other obstructions on the track-itis de-" sired to raise the arms 28, this'can be done by a slight upward movement of the handles 42, which will raise the bars 26 out of contact at their lower ends with the upper ends of the arms 28 when the springs 39 will turn the same inwardly on their hinges, so as to assume the positions shown by dotted lines in Fig. 1 of the drawin s. When the said arms are in their lowered positions, it is apparent that the instant two cabsor' cars are on the same track ,and within the zone of in' fluence they will be electrically connected matically sounded in each of the cabs or cars, for it will be understood that the electric current will. pass from one of the cabs through the upper conductor 18, from thence through the upper contact device 37 or 45, from thencethrough the conductor 34 to the battery 48, and from thence through the conductors 64, contact-springs 62 and 61 at one side of switch 52, and conductor 67 to the alarm 49, andfrom thence through the conductor 66, contact-springs 58 and 59 at the other side of switch 52, an and lower contact device 37 or to trackconductor 19, and from thenceby a reverse course through the similar parts of the other cab or car. When the circuit is 'thus completed, the alarm on both cabs or cars will be sounded, and if the engineers or persons on the cabs or cars desire to communicate with one another the push-button of the switch may be pressed inwardly, so as to force the springs 59 and 62 into contact with the springs and 63, respectively, which operation will cut out the alarm 49 and simultanethence by way of conductor 35 I ously throw the telephone 50 into circuit, so

that it may be used on either or both'of the cars.

Having thus fully described-my invention,

' hat I claim as new, and desire to secure by I Letters Patent, isv 1.
